Cristiano Ronaldo has showed off his incredibly toned physique while holidaying in Miami

Cristino Ronaldo has clearly been putting in extra time at the gym – as his latest topless appearance shows.

The football star, 28, showcased a rippling physique as he hung out with mates on a private yacht in Miami on Monday.

The star took to Twitter this weekend to let his fans know how much fun he is having in the American sun, saying simply: ‘Vacations, friends, fun.’

The Portuguese hunk has been well known for his tough self-imposed work out regime which is said to include 3,000 sit ups a day.

A friend of the fitness fanatic revealed back in 2009 ‘He can spend well over an hour every day toning his abs, sometimes while watching telly’ – although his latest profile would suggest he may have stepped up his work outs even further.

His time off in the States is likely to be a welcome distraction while he mulls over his next career move.

Cristiano has reportedly been advised to sit tight at his current team – Real Madrid – being recommended to remain with the team for a further 18 months before transferring to Manchester United.

It would make financial sense for him to do so, as his value would increase (reportedly to £60 million) if he sits out his current contract.
